The RECTORSEAL 150MW4X10 is a two-way floor supply grille designed for residential HVAC systems where controlled directional airflow is needed at floor-level duct openings. Built from stamped steel with a white powder-coated finish, this grille fits a 4-inch by 10-inch floor duct opening. The two-way louver configuration splits and directs air discharge across the floor plane, supporting balanced room air distribution. Licensed HVAC technicians and residential installers specify this type of grille for supply-side floor register applications where durability and a clean painted finish are required.
This grille is suited for residential forced-air HVAC systems using floor duct runs, a common configuration in slab-on-grade construction and basement-ducted homes. It is installed at the duct termination point in finished flooring and provides the visible register face in living areas, hallways, and bedrooms. The white powder-coat finish allows it to blend with standard interior trim without additional painting or finishing work.
Designed as an OEM-style replacement or new-installation floor supply grille for residential forced-air HVAC systems with 4-inch by 10-inch floor duct openings.
Installation is typically performed by a licensed HVAC technician or qualified contractor. Power down the air handling system before beginning register work. Ensure the duct opening dimensions match the grille boot before securing the unit. Follow applicable local mechanical codes and manufacturer guidelines for floor register placement and fastening.
